About me:

I am a telecom engineer by formation (2004), got a PhD in computer science (2008), both at Grenoble University (France). I worked on WiFi access methods in the layer two (MAC) during my PhD, to improve fairness, which was a pertinent research problem back then when WiFi was still in its 802.11b and 802.11g version of the standard.

After some errands in a early stage startup working on push notification during the early years of the iPhone (2009), I joined a catalan research lab (CTTC) in Barcelona (Spain) in 2010. Quickly, I joined the research group of Telefonica I+D, the R&D unit of the spanish tier one operator, where I worked on energy consumption of mobile phones, and publish a couple of papers with great folks. I like research, but I felt it was important to have a more tangible impact.

With the wind down of the Telefonica Digital unit, I explored some opportunity at Qualcomm as Product Security Engineer in their great QPSI group, before joining back Telefonica, this time working on innovation projects as individual contributor. Got the great pleasure to work on the Internet Para Todos initiative, to assemble open efforts (like Magma) or new technologies (like Loon, now defunct, which has now released some strastopheric data on their LTE balloons flights over the test areas!) to provide connectivity to low ARPU areas, and learn a lot on the reality of the telecom business (it is not only a technical, but a business and regulatory design space as well).

During that time I grew some taste for infrastructure work, with operating lab level Openstack and Kubernetes clusters, and packaging vendor software as NFV and pods using some Hashicorp tooling (packer, terraform…), and learning a lot on automation with tools like Ansible.

Since 2019, I went back to exploring with some opportunity with the Nefeli folks to work on Lean NFV, but decided to join the Working Group 2 folks, a scandivian startup to work on their 4G/5G public cloud based core product. My focus those days is to build a more minimalistic, cloud native, MME/AMF/SGW/UPF functionality, leveraging modern tooling, languages and infrastructure environments like Kubernetes.
